Buying Guide
- Goals and ingredients: Match products to goals such as strength, muscle mass, recovery, or performance. Look for evidence-based components (e.g., creatine monohydrate, leucine, HMB) and assess whether the product offers clear dosing guidance.
- Form and convenience: Capsules and tablets can improve adherence for daily use, while powders may suit those who prefer flavour customization. Consider swallowing ease, taste, and travel practicality.
- Quality and certifications: Check for third-party testing, vegan or Halal certifications where relevant, and transparent ingredient lists. Certifications can indicate quality control standards.
- Lifestyle compatibility: Vegan, halal, or allergen considerations can influence choice. Also consider any medical conditions or medications that could interact with supplements.
- Timing and stacking: Some products are suited for pre-workout, post-workout, or daily use. When stacking, ensure ingredient overlaps do not exceed recommended daily intakes and avoid unnecessary redundancy.
- Budget and usage period: Calculate cost per serving and total monthly cost. Long-term consistency often yields better results, so choose a formula that fits your budget.
- Evidence and expectations: Distinguish between clinically supported ingredients and marketing claims of immediate results. Use realistic timelines and combine supplementation with solid training and nutrition.
